Does the E10 support Special Bits like the other please? if so how can i add one.
also, I'm designing a surge protector for industrial air compressors, i have the plc connected to the unit CT to 24V. i like to add a suppressor to the supply voltage, can you guys recommend a type of suppressor i can use.
Thanks,
Regards,

E10 support a few special bits although less than those found on the H-series and M-series. When you insert a contact you can scroll using left/right cursor key and click on the drop down menu to select special bits table.
I am not sure how your surge protector work but do take note that E10 does not have analog i/os. For surge suppressor consider one of those Transorb that can work rapidly to absorb voltage surges on the AC lines.

I'm just detecting a Transfer switch from Normal power to Emergency power. that occure in 10 ms so the units stays with no power for 10 ms.
I programmed the E10 and it detect the voltage drop faster than my eye can blink it worked. i just need it to add the suppressor to protect the plc.
in my version of winTRiLogic 3.5 for the E10 i don't get that table with the Special Bits. i can see it but can't select it.
Thanks.

You should be able to select the special bit (sequencer or clock pulses) when you are creating a contact. For E10 only a few of the special bits are available. The rest are shown as "-"

Sure, I see the Special Bits on the Drop down box but is not allowing me to select it. I click on it but it goes back to the previously selected item.
Thanks.

The picture I show to you above is when I try to insert a series contact and I picked up the Clk:1.0s special bit from the menu and it was inserted into the ladder circuit.
What were you trying to connect? Did you try to connect it as a coil? The special bit here can only be used as a contact on the ladder diagram and not used as a coil.

I also use the WinTRiLOGIC for the TM888+ too. I'm doing the same thing as you're showing me. But it doesn't work even if i click on the side arrows it doesn?t go over counters.
I will re-install the program again.
Thanks.

What version of O/S are you running? What version of JRE is being used? Hopefully a re-installation will work.
